Just tried running a MKV that is 1080p (1h37m 8,1GB).In LMCE 7.10 this file does not work, playback is choppy and green.In LMCE 8.10 this file works and CPU is at max load (a bit choppy in demanding scenes, no greenies)

For fun I installed Ubuntu 9.04 on the same machine, installed updates, and enabled the stock 180 driver.Tried playing the same MKV and of course it searched for a codec and installed that.The file plays great, and Totem is using 37% CPU -+ a few.

Is VDPAU working out of the box in Ubuntu/Kubuntu 9.04?Anyone know how I can see if Totem is using VDPAU?

I went to the KDE desktop, to the directory with the files, clicked the trailer I am Legend.m2ts, choosed mplayer in the with window, using to it shows gmplayer and played the movie, perfect, cpu usage was most 20%.

Played the transformers.m2ts file, in the same manner, cpu usage was most 40 to 50 percent, sometimes spicking to 83% but quickly returning to to 40 to 50 average. There were drops to 20% during quiet scenes.

Guys, I apologize for my second to last post, poor english; one of those mornings.

An update:

I backed up the mplayer binaries listed in my previous post, copied the new binary into those respective locations; only achieved crashing CORE, MD, the whole system. Well rebooted and fix my error, system is operational.

Still am unable to experience VDPAU in linuxmce! Through further investigation, saw below:

I had a hectic week, thus did not get chance to check out your recommendations.

I searched for the source, and found the Mplayer_Player source.

Will attempt as your suggestions; was also looking at passing the options in the call to initiate mplayer, using vdpau and the codecs as you use when playing from desktop, recompile Mplayer_Player, hopefully could only change this on the MD, so if I break it, it does not screw in install - do not have the time to rebuild.
